At its core, routing is one of the most fundamental concepts you need to master.</p> <h2>Basic Route Structure</h2> <p>Express routes follow a simple pattern that combines HTTP methods with URL paths:</p> <pre><code>{` app.get('/users', (req, res) => { res.send('Get all users'); }); `}</code></pre> <h2>Route Parameters</h2> <p>Dynamic routes can be created using parameters:</p> <pre><code>{` app.get('/users/:id', (req, res) => { const userId = req.params.id; res.send(\`Get user \${userId}\`); }); `}</code></pre> <h2>Middleware Integration</h2> <p>Routes can include middleware functions for additional processing:</p> <pre><code>{` const authMiddleware = (req, res, next) => { // Authentication logic next(); }; app.get('/protected', authMiddleware, (req, res) => { res.send('Protected route'); }); `}</code></pre> </section> <footer> <div class="tags"> <span class="tag">Express.js</span> <span class="tag">Node.js</span> <span class="tag">Web Development</span> </div> <div class="share"> <h3>Share this article</h3> <nav class="social-links"> <!-- svelte-ignore a11y_invalid_attribute --> <a href="#">Twitter</a> <!-- svelte-ignore a11y_invalid_attribute --> <a href="#">LinkedIn</a> <!-- svelte-ignore a11y_invalid_attribute --> <a href="#">Facebook</a> </nav> </div> </footer> </article> <style> .blog-post { max-width: 800px; margin: 0 auto; padding: 2rem; } .metadata { color: #666; margin: 1rem 0; } .content { line-height: 1.6; } .tags { margin: 2rem 0; } .tag { background: #eee; padding: 0.25rem 0.5rem; border-radius: 4px; margin-right: 0.5rem; } pre { background: #f4f4f4; padding: 1rem; border-radius: 4px; overflow-x: auto; } </style>
